Construction of tall buildings in excess of 200m in height has become increasingly common and  mega foundation systems are generally required to safely support the large lateral and vertical building loads and to control total and differential movements of the foundation.

Aims and Objectives
Foundation and building behaviour is highly interactive, with movements of the foundation resulting from the building loads, and these movements in turn influencing the behaviour of the building.  Foundation behaviour is mainly governed by the prevailing ground conditions, the foundation type,  magnitude and distribution of the building loads.  The foundation design of tall buildings should therefore be considered as a performance based soil-structure interaction issue and not limited to traditional empirically based design methods.
